[0002] Instruments and meters are devices or equipment used to detect, measure, observe and calculate various physical quantities, material components, physical parameters, etc. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In a broad sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission and data processing. For example, pneumatic control instruments and electric control instruments used in automatic control of industrial production processes, as well as distributed instrument control systems, are also instruments and meters.

[0003] Since instruments are composed of numerous electronic components, a shell is used to install and protect the completed instruments. After long-term use, the heat generated by the internal electronic components of the instruments will cause the temperature inside the shell to rise, which will easily cause a large temperature difference between the inside and outside of the instrument, thereby causing water mist to form on the display screen of the instrument and the inner wall of the shell. The water mist will affect the service life of the electronic components inside the instrument. Utility Model Content

[0036] In this embodiment, the side wall of the mounting plate 310 is provided with a guide plate inclined toward the display assembly 110, which is used to guide part of the fast-circulating air generated when the electric fan 320 is working to the display assembly 110, thereby avoiding the generation of water mist at the display assembly 110 to damage the display assembly 110.

[0037] In this embodiment, the specific usage process is as follows: the electronic components of the instrument are installed and protected by the cooperation of the outer shell 100 and the base 200, and the defogger mechanism 300 works to allow the air inside the outer shell 100 to circulate quickly with the outside, thereby quickly cooling the inside of the outer shell 100 to reduce the temperature difference between the inside and outside, and at the same time, dry a small amount of mist inside the outer shell 100, thereby avoiding the influence of the mist on the electronic components inside the outer shell 100.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
